`SPECIFICIA'IIOIJ forming part of Letters .Patent No. 291,417, ldated January 1, 1884.

` `Application filed September 5, 1852. (No modele freshly-charged coal-gas retorts in gas-.houses have usually been allowed to pass directly into V the hydraulic main,where they are condensed into tar, and are thereby lost as material for gas-making. In a few cases only these vapors are utilized for gas by drivingthem from one retort or chamber1 inwhich they have originated into an adjoining and reciprocating retort or chamber, in which the distillation of coal is further advanced. For this purposethe retorts are arranged in pairs and connected by pipes and passage-ways. The condensable vaporseoming from the last-charged retort are made to pass into the twin retort or chamber by taking advantage of their own tension or pressure, or

they are blown into the latter by jets of steam.

In the first case the vapors are not removed fastenough from the distilling-retorts to relieve them promptly of the pressure. In the latter case,when steam is used as the sole propelling agent, it results in sucha large admixture of steam with the tarry vapors that the resulting gashas its ill uminati n gpower th ereby reduced.

The object of my invention is to convert these 'tarry vapors, as they are given off from the fresh charges of bituminous coal in gas-retorts during the early part of the distillation, into a fixed gas by injecting them into a separate re tort filled with incandescent coke, and driving them through the mass of said coke by means of the combined action of a jet of compressed gas and a comparatively small jet of steam. The coke-retort, in which the tarry vapors are convertedinto gas, Icall the regeneratoiz lI attain the object of 4my invention by the apparatus shown in the accompanying drawings, in which` Figure 1 isa perspective View of my plant for making coal-gas by my improved method, and Fig. 2 is a vertical section ofthe combined l steamand gas injector j and pipes dandllvand u and s.

` In mygas-plant the stand-pipes c au, 6to., communicate with the large horizontal con necting-pipe which is just above the standpipes. From the pipe ci a short vertical pipe, cl, reachesV down into the top of the regenerating-retort r. The injectorj has its steam-jet andgasjet :nozzles exactly over the mouth of downward-into the said mouth.

`o `010, &c., are valves for opening andclos: ing the stand-pipes. c c e, are pipcswhich lead from the stand-pipes o a a, dre., to the hydraulic main h. below the valves o o o o, and carry the gas from the stand-pipes directly to thehydraulic main when the valves o 0 o o are closed.

C is the standpipe that comes from the rear end of the regenerator r. It carries the gas vfrom the latter into the water-main.

The mode'of operation in applying my invention is as follows: The regenerator r is at certain intervals-say every six hours-filled With coke, and is constantly kept at a brightred heat. The distilling-retorts p q, Svc., are charged with bituminous coal at certain intervals as follows: If the time allowed for the distiilation of the gas in each retort be equal to 7L hours, and if there are, for instance, twelve retorts connected with one regenerator, then one of the distilling-retorts ought to be charged every Tl? hours. If, therefore, the time for distilling each charge be six hours, then thetime from the charging of one of the distilling-retorts to the charging of the next succeeding one ought to be or one-halfhour. Now,si1pposing the retort p hasj ust been ch arged ,then the valve o, Fig. l, that belongs to the stand-pipe of this last-charged retort, p, is opened and kept open for some time, in order to let the tarry vapors given Off from the said last charge of coal pass into the main connecting-pipes cl and d', and through them into the regenerator r. Afteronehalf hour the next retort, q,'is charged With bituminous coal. Then the valve o that belongs to the stand-pipe connected with the retort q is opened, &c. The-valve o in the stand-pipe belonging to the first-chargedretort, p, is then closed, in order to cause the gas produced in the retort p (which is by this time a permanent gas) t0 pass directly into the hydraulic main h The ta a the stand-pipesjust the vertical pipe d, both of them pointing y ICO by means of the pipe c. After one-half hour more another retort is charged with fresh coal. Then the valve o in its stand-pipe is opened, While the valve o in the stand-pipe belonging to qmay then be closed, &c. Thus the tarry vapors that arise from one fresh charge of coal after another are made to pass for a certain length of timeinto the connecting-pipes d and hd', and from the latter they are blown into the regenerator r. The injecting of the vapors into the regenerator r and through the mass of incandescent coke in the same is effected by the combined action of a jet of compressed gas and a small jet of steam, both of which issue together from the nozzle of the injector j, inside of the pipe d, with sufficient force to propel the said vapors into and through the coke. By their contact With the incandescent coke in the regenerator r the tarry vapors are converted into a Xed gas fit for lighting and heating. Now, I do not claim, broadly, to convert these vapors into gas by driving them into and through other more highly heated-retorts than those are from which they have originated, nor the reciprocating action between retorts arranged in pairs Where these vapors are generated in one retort and converted into gas in the mate of the former, and vice versa, nor do I claim the application of steam by itself as the sole means for injecting the tarry vapors into the regenerating-retorts.

What I claim, and desire to secure by Let ters Patent, is

1. The improvement inthe process of manufacturing gas,which consists in converting the tarry vapors given off from fresh charges of bituminous coa-l in gas-retorts, during the early part of the distillation, into a fixed gas by injectingsuch vapors, by the combined action of a jet of gas under pressure and a small jet of steam, into and through a mass of incandescent coke in a separate retort, substantially as shown and described.

2. In a plant for manufacturing coal-gas,the combination, with the common distilling-retorts p q, the stand-pipes a a, and the hydraulic main lz', of the connecting-pipes d and d and c e e e, the gas and steam pipes s and u, the injector j for gas and steam, and the regenerating-retort o', all substantially as shown and dcscribed.
